Describe a method for refining nickel. |
|
Answer» Solution :For REFINING nickel is heated in a stream of CARBON MONOXIDE forming volatie complex (nickel tetracarbonyl). `Ni + 4CO overset(330 - 350K)to Ni(CO)_4` The carbonyl is subjected to high temperature so that the complex DECOMPOSES to give the pure metal. `Ni(CO)_4 overset(450 - 470 K)to Ni+4CO` This process is called Mond.s process. |
